H'UEGLIN,OI CHICAGO, ILLINOIS, ASSIGNOR TO FEDERAL MERCHANDISE COMPANY, OFCHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS VENTILATING MEANS Originalapplication filed June 80, 1928, Serial No. 289,573.

' Serial No. 440,687.

This invention relates to ventilating means, and more particularly to abracket for mounting the motor and fan of a ventilating means fordomestic use.

It has become the practice in kitchens, and

other similar rooms, to mount an exhaust fan in the upper part of thewindow so that the Warm air, steam and odors from cooking may beexhausted from the room through the operation of the fan. In mycopending application, Serial No. 289,573, filed June 30, 1928, Idisclosed a ventilating means of this type. The present application,which is a division of said copending application,

relates specifically to the mounting ring and bracket for encasing themotor and supportin the motor and fan in the panel structure.

gince the motor and fan project into the room of the residence, andsince they are plainly visible when installed in the manner pointed outin my above mentioned copending application, it is imperative that thebracket for supporting the motor and ,fan be of pleasing appearance sothat its installation will not detract from the beauty and harmony ofthe room. Furthermore, it is desirable that the device be as free aspos- Qsible from sharp corners and cracks into which dust and dirt cancollect so that it may be easily cleaned by the housewife. "To'this end,I have provided a new and improved mounting for the motor and blade ofan exhaust type fan, a mounting which particularly adapts itfor use inventilating panels that are to be inserted in windows of residences andother similar installations.

Now to acquaint those skilled in the art with the teachings of myinvention, refer encevis made to the accompanying drawing in which apreferred embodiment of it is shown by way of example and in which:

Figure 1 1s a perspective view of the mounting bracket; and

Figure 2 is a cross-sectional view of me bracket taken through themounting ring, one of the arms and the motor mounting cup.

As will be seen from the drawing, the mounting ring 1 which is used tosupport the motor andfan in the panel or othefry'similar 5Q device-uponwhich the ventilating niean's is to be mounted, comprises a circularring having a flange portion 2 projecting outwards adj acent one of itsedges. This ring 2 is annular in shape and is provided with screw holes3 through whichscrews' or bolts may be projected to mount it upon apanel su port. The mounting ring 1 also is provi ed with a cylindricalmember formed integral with the annular flange screw and projectingbeyond both surfaces of that flange. The one proj ection 4 serves as amounting guide to position the bracket in an opening in the panel uponwhich it is to be mounted, and the other projection 5 serves as a guardfor the fan blades of the ventilator.

The motor casing 6 is a cylindrical member closed at one end 7 and openat the opposite end 8 which open end is disposed adjacent the mountingring 1. The motor housing 6 is attached to the mounting ring 1 by aplurality of arms 9 which rise out of a flange projection 5 of themounting ring and terminate in the edge of the motor housing 6 adjacentits open en 8.

Preferably the mounting ring 1, its flange 2 and projections 4 and 5 andthe motor housing bracket 9 and the housing 6 are all cast as anintegral structure, and are preferably cast out of aluminum, an aluminumalloy, or brass, although if desiredftthis structure might well be madeout of an insulating material. such as a phenol condensation productwithin the teachings of my invention.

The electric motor indicated generally at 10 is encased in the casing 6,and held therein by a collar 11 which is a part of the motor and whichis fitted into the counterbore 12 in the open end of the casing 6, whereit is held by any preferred means such as the screws13.'- As shown, themotor is of the squirrel cage induction type, and has but a singlebearing 14, this showing being made by way of ex ample as any preferredtype of motor of suitable size may be encased in the casing 6 within theteachings of my invention. The laminae 15 of the stator of the motorform an outer casing for the motor, the outside diameter of which issuch that it will easilv fit in the easing 6, these laminae beingrigidly attached to the cover plate 11 in any preferred manner.
